Covered Philippine taxpayers must comply with electronic invoice issuance requirements on or before 31 December 2026, under Section 2 of Revenue Regulations (RR) No. 26-2025.
For business owners, preparation begins with understanding whether the requirement applies and assessing what needs to change. Before purchasing software, review your taxpayer classification, business activities, existing systems and invoicing procedures.
01Who needs to comply?
RR No. 26-2025 identifies the following principal categories:
| Category | Taxpayers covered |
|---|---|
| E-commerce or internet transactions | Taxpayers classified as Small, Medium or Large |
| Large Taxpayers Service | Taxpayers under the jurisdiction of the BIR's LTS |
| Large taxpayers under the EOPT framework | Those classified as Large under the Ease of Paying Taxes Act and RR No. 8-2024 |
| Specified accounting and invoicing systems | Taxpayers using CAS or CBA with Accounting Records (with electronic invoicing), and other invoicing software |
Exporters, registered business enterprises enjoying tax incentives, and POS users have separate transition provisions. Check whether another covered category or an existing directive already applies to the business. Their status alone should not be treated as automatically determining the December 2026 deadline. Reference: RR No. 26-2025, Section 2.
Micro taxpayers are excluded from the stated mandate. However, a later downgrade in classification does not automatically end an existing obligation. Reference: RMC No. 98-2026, IV(1) and IV(16).
02How do you determine your taxpayer classification?
Under RR No. 8-2024, the classification thresholds are:
| Classification | Gross sales for the taxable year |
|---|---|
| Micro | Below ₱3 million |
| Small | ₱3 million to below ₱20 million |
| Medium | ₱20 million to below ₱1 billion |
| Large | ₱1 billion and above |
Gross sales are measured net of VAT, where applicable, without other deductions, and cover business or professional income subject to the regulation's exclusions. These classifications concern sales, not net profit or capitalisation.
Review your recorded BIR classification and any reclassification notices. Do not assume that a change in annual sales automatically changes your classification. RMO No. 37-2024 provides the relevant procedures.
03Does an emailed PDF count as an electronic invoice?
A PDF alone does not establish compliance. The underlying system must meet structured-data, electronic-delivery and processing requirements. Manually prepared Word or Excel invoices do not qualify. A PDF customer copy is not, by itself, prohibited. Reference: RMC No. 98-2026, IV(4)–(7).
Ask your provider to demonstrate how an invoice is created, delivered, retrieved and reconciled. Reviewing the invoice's appearance alone will not establish whether the system meets your requirements.
04Which permits and operational requirements matter?
| Requirement | Applicable provision of RMC No. 98-2026 |
|---|---|
| Obtain a Permit to Issue Electronic Invoice before issuance; CAS authority alone is insufficient. | II(7), IV(12) |
| Secure EIS Certification within six months of PTI issuance. This does not extend the invoicing deadline. | IV(15) |
| Include the head office and branches; assess permits for distinct systems. | IV(10), IV(13) |
| During downtime, issue authorised manual invoices, then replace them with cross-referenced electronic invoices upon restoration. | IV(11) |
| Distinguish invoice issuance from sales reporting, which follows applicable BIR implementing directions. | IV(2), IV(15) |
These requirements should be incorporated into the implementation schedule.
05Seven practical steps to prepare
The following are recommended implementation steps, rather than a separate list of mandatory BIR requirements.
1. Document your coverage assessment
Prepare a working paper identifying your taxpayer classification, sales channels, business activities, branches and current systems.
Record the basis for your conclusion and resolve uncertainties with your accountant and the appropriate BIR office. Assign someone to monitor subsequent issuances.
2. Map your invoicing process
Follow an actual transaction from the customer's order through invoicing, collection and accounting.
Identify missing customer information, repeated manual encoding and differences between sales records and accounting reports. This will help establish what the proposed system must handle.
3. Assess your existing software
Ask your provider whether your current system can be upgraded and request a written implementation proposal.
Compare the available options based on:
- Setup, subscription and support costs;
- Accounting, inventory and payment integrations;
- Branch access and user permissions;
- Data export, backup and migration;
- Training and implementation time; and
- Responsibility for applications, testing and updates.
RMC No. 110-2026 establishes accreditation and continuing compliance requirements for electronic-invoicing solutions offered by Electronic Invoicing Service Providers. Request documentary evidence of any claimed accreditation and verify its applicability to the proposed solution. The existence of the framework does not establish that a particular provider has been approved.
4. Review your customer data and tax settings
Check customer names, addresses, TINs, branch details, product descriptions and applicable tax treatment.
Have your accounting team review the configuration. Software installation should include checking that transactions are recorded consistently with your business's tax and accounting requirements.
5. Test realistic transactions
Use examples from your operations, including discounts, returns, different tax treatments and branch transactions where relevant.
Trace each test transaction through the invoice, accounting entry and collection record. Keep an issue log and retest after corrections.
6. Train staff and prepare for interruptions
Assign responsibilities for invoice issuance, customer-data checks, error handling and escalation.
Document the steps staff should follow during system interruptions. Test whether they can retrieve records, identify unresolved transactions and reconcile records after service is restored.
7. Work backwards from the deadline
Set internal target dates for system selection, documentation, applications, testing and training. Allow time to resolve issues before implementation.
Use a simple tracker showing each task, responsible person, target date and evidence of completion. Track subsequent certification requirements separately.
A final readiness check
Before implementation, management should be able to answer:
- Have we documented why our business is covered or excluded?
- Have we identified the applicable permits and certification steps?
- Has the system been tested using our actual transaction types?
- Have accounting personnel checked customer data and tax settings?
- Do employees understand their responsibilities during normal operations and interruptions?
- Can we retrieve and reconcile invoice records?
